1 Features
The WAMIX range of vacuum mixers range can be used for mixing all types of
plaster, embedding and silicone-based materials, and vacuum-washing of models
for special dental procedures.
There are separate power units for vacuum generation and mixing. A timer is used
to switch the mixers on and off without breaking the vacuum.
Until changed, the set mixing time (up to 240 seconds) becomes the default. An
audible signal indicates the end of the mixing process.
The mixing beakers on these units are held to the flange only by vacuum,
guaranteeing air is excluded.
The mixers are supplied for wall-mounting but can readily be converted for tabletop operation at any time (for accessories, see 8.4).
The WAMIX-3M also features a pressure chamber, allowing you to achieve a
more homogeneous, blister-free texture by hardening materials under pressures
above atmospheric.
The WAMIX-2M also has a vibrator for preparing single spoonfuls, for example.

i
Ensure that this user manual is accessible at all times and has
been read and understood.
3 Area of application
WAMIX mixers are used for mixing under vacuum all types of plaster, embedding
and silicone-based materials.
They can also be used for vacuum-washing models for special dental procedures.
The insulating layer between the model and the prosthesis does not peel off
prematurely, because the model is kept moist better than when washed in a
pressure embedder.
The WAMIX-3M can also produce more dense material using pressures above
atmospheric. When materials (embedding and silicone-coated materials) are
hardened under pressure, any residual air in the mix is compressed, resulting in a
more homogeneous, blister-free material. This is the best basis for smooth casts.
The WAMIX-2M has a vibrator which also allows you to prepare single spoonfuls,
for example.
4 Before you start
4.1 Unpacking / Transport
− Remove the packing materials and place the unit on a firm, level surface or use
the supplied bracket to mount it on the wall. Check that all items have been
supplied (see 8.4).
− Before transporting the unit, ensure that it has been unplugged from the power
socket.
damage.
Make sure that it is packed correctly in order to avoid accidental
- 6-
4.2 Location / storage
− Set the unit up on a level surface or mount it on the wall.
− If mounting it on the wall, check first that the wall can take the weight. Mark out
the hole template by removing the bracket from the unit and using it as a guide
for drilling the 8 mm ∅ wall plugs. Leave a free area of at least 25 - 30 cm
under the unit.
− Always ensure that the work area is large enough for easy operation (allow for
the unit’s size) – do not set the unit up out of doors!
− If the unit is to be stored for an extended period, protect it from moisture and
dust.
− Connect the following before you turn the unit on:
1. Plug the power cord into the socket, making sure that the mains voltage
matches the mixer.
2. WAMIX-2 and WAMIX-3M only:
Connect a compressed-air hose in accordance with the technical
specifications. In the case of long hoses, make sure that the hose ID is at
least 6 mm. Provide a monitoring unit for each air hose and use a
pressure gauge to keep the pressure constant.
i
Accidental mixing is not possible because the motor starts only
after the beaker is held by vacuum to the flange, even if a mixing
time has been set.
Before you use the vacuum mixer, check that the lock plate (under
!
the unit) has been turned through 90° (it should protrude beyond
the housing). Tighten the screw on the plate to prevent the unit
coming loose accidentally.
- 7-
5 Start-up
− Turn on the green switch (vacuum mix) ( all WAMIX models)
− Open the compressed-air supply (WAMIX-2 and WAMIX-3M only)
− WAMIX-2 only:
When you use the unit for the first time, you will have to adjust the vacuum
using the regulator knob. A pressure of at least 5 bar is recommended. The
regulator knob is located under the pressure gauge. Open the valve slowly, until
the arrow moves from zero into the green range. The best vacuum is obtained
in the middle of the range, not when the valve is fully open. Re-adjustment is
only necessary if the compressed-air supply changes in some way.
− WAMIX-3M only:
Use the regulator (black knob to the left of the vacuum flange) to set the
pressure for embedding – max. 7 bar (safety valve). Pull and turn the knob to
set the desired pressure. The initial pressure will be the maximum sealing
pressure. Push the knob in again.
NOTE: If you want to set a lower pressure, first turn the unit off (vent the unit),
because the tank pressure is kept constant by a non-return valve. Then set the
desired pressure on the gauge by turning up the regulator.
i
WAMIX-2: If, when you are setting the pressure, the arrow on the
pressure gauge does not enter the green range, there is too little
flow to the unit. Check the compressed-air supply (see also 4.2).
i
If the unit is not to be used for an extended period, disconnect the
compressed-air supply and turn the mixer off.
- 8-
6 Operation
i
All instructions for using the unit, whether verbal, written or in the
form of practical guidance, are based on individual experience and
experimentation and can only be regarded as guidelines.
6.1 VACUUM MIXING (all WAMIX models)
1. Set the mixing time (up to 240 seconds) (automatic operation). This time is
used until a new time is set. For manual operation, turn the timer to 0, but set
the desired mixing time only after a vacuum has been obtained.
2. Add the material to be mixed to the beaker.
3. Add the liquid and mix manually until the powder and the liquid are well
combined.
4. Seal the beaker with the lid.
5. Insert the beaker into the mixer from below. This will start the vacuum suction.
Hold the beaker until a vacuum is obtained.
6. The mixer will switch on automatically for the set time. An audible signal will
indicate when mixing has finished.
7. Hold the beaker firmly before turning off the switch (vacuum). The beaker will be
released from the mixer as the vacuum drops.
i
The sealing surfaces between the beaker and the cover must be
clean – likewise the rotor mounting spigot and the top of the
beaker cover – to ensure trouble-free operation.
i
Fill the beaker only to the Max. mark. Otherwise, too much material
will be drawn into the system by the vacuum.
- 9-
i
After the vacuum has dropped, the beaker will come away by
itself. To avoid damaging the seal, never pull on the beaker.
6.2 PRESSURE EMBEDDING (WAMIX-3M ONLY)
1. Set the time on the timer (up to 60 minutes).
2. Open the black latched door (turn in the opposite direction to the arrow) –
do not try to pull it open!
3. Insert the items - max. 3 large muffle rings.
4. Close the pressure chamber and activate the green switch (embedding).
5. The pressure will rise to the set level (pressure gauge).
6. When the set time expires, the pressure chamber will vent automatically, and
the items can be removed. The pressure-embedding process can be
interrupted at any time by turning off the switch (embedding), that is, the
pressure chamber will be vented.
i
If the pressure drops in the compressed-air supply hose while the
mixer is running, the non-return valve will keep the pressure at the
level already reached.
Open the pressure chamber only when the pressure has fallen to
i
zero. Opening the chamber prematurely can tear the rubber ring
from its groove and damage it.
6.3 VIBRATOR (WAMIX-2M only)
1. Press the white switch (vibrator).
2. The vibrator rod and rubber ball vibrate.
3. Hold single spoons (or small moulds) against the rubber ball and add the mixed
material (plaster and similar) in small amounts. This allows you to use the one
mixer for smaller jobs.

8 Maintenance
8.1 Cleaning
The unit should be cleaned at regular intervals to ensure problem-free operation.
It requires only normal cleaning (sponge, damp cloth, mild detergent). Do not use
chemical additives.
Solvents must not be used to clean the mounting plate!
Keep the beaker clean. When not in use, fill with water to just below the stirrer.
The model plate must always be legible and should not be removed.
8.2 Servicing
i
Allow the condensors to discharge before you open the mixer.
Our vacuum mixers do not require servicing. Just make sure that the unit is kept
clean and that the flange seal is not damaged.
Changing the filter:
Undo the knurled screw (on the right, near the mixer on the vacuum flange on the
underside of the unit). The filter swings loose at the forward end of the screw. After
changing the filter, do up the screw finger-tight (do not forget the O-ring).
8.3 Warranty
The warranty period for our instruments is 6 months. If faults occur within the
warranty period, contact your dental depot or get in touch directly with our Service
department.
Vacuum mixers should only be operated in perfect condition. If faults occur which
- 12 -
could harm operators or third parties, the unit should not be used until it has been
fixed.
The warranty does not cover damage caused by improper use, external
mechanical causes, transport damage or interference with the unit by
unauthorised persons.
